The referenced script on this Behaviour is missing!

I’m getting this warning. I’ve tried the ‘FindMissingScripts’ script from the wiki, but it couldn’t find the problem. What else can I do to fix this? Thanks.

Check your gameObjects. One by one.

I think it is an Unity bug because I get this warning from some gameobjects none of which had an script ever attached.

The thing is happen when you attach a script with any game object but later that script is removed from the Project window. Thats why It show warning.
